Toall whom it may concern-.- 5

Be it known'that we, EDWIN H. ALLFREE and (VILLIAM H. ENGLAND, citizensof the United States, residing atChicago, in the county of Cook andState of Illinois, have invented certain new andusefullmpr'ovements inDerailers, .of which thc'followingis a specification. V

()ur invention relates to improvements in derailing devices of the typeadapted to lift the wheels of a car from the rail and guide themdiagonally away therefrom.

Theobjects of the invention are, firstjto provide a derailersoarranged'that a car may safely run backward over it without dera'ilment; second, to construct an eflicient device of the ty e. describedwhich may be entirely supporte for o eration from the bottom flange ofthe rail third, to provide an im'- roved operating mechanism constructedas sclosed with a tumbling motion fondisposinglthe; device in operativeor idle position at Further objects are to provide increasedefiiciencyand durability of the apparatus,

vantages which will more fully appear hereinafter.

, Theinvention consistsin structural embodimentsof the above featuresand in a specially effective. relative arrangement of parts, all ofwhich will be more particularly deecihcation and then clearly pointedout in t e appended claims."

Referring to the accompanying two sheets .of drawing in which the samereference char- At 1 is shown a section of arail acters refer to thesame parts in the several ures: Figure 1,1s a side elevation of thedevice clamped to a rail and in operative positionthereon; Fig. 2, is alike view showing the initial movement of parts in throwing the derailerto idle position; Fig. 3, is a similar view showing a further -movement,while F ig: 4, shows the deviceresting in idle or inoperative positionwhen as appears a wheel -may pass without touching the derailer;

connecting rib 5 therefor, this latter forming the bracket into onesolid piece. The bracket 2 has arranged to co-act therewith for clamlength to accommodate different sizes of rails or different sets ofbolts may be substituted as is obvious to enable a wider rangeofadjustm'ent. .The arms 3, 4, of the bracket 2 are providedwith afulcrum bolt 11, secured in holes 12, 13 therein, and extending betweenthe arms. Said arms are further provided with channels 14,15 on theirinner side faces and with slots 16, 17 in their. upper edges all for'theurposes hereinafter made plain. The derai ing piece 18 carries twosupporting arms 19, 20 and two operating arms 21, 22. It is arranged toswin with a tumbling movement between the racket arms 3, 4 and for thispur osethe supporting arms 19,20 are provided with lugs 23, 24 arrangedto engage and move in said channels 14,. 15, and with curved slots 26arran ed to receive the said fulcrum bolt 11 and guide the derailingpiece thereon in its movement. The supporting arms 19, 20 of thederailing piece are further 'rovided with projections 27, 28, sodisposed tiiereon that they will engage with the slots 16, 17' when thederailing piece is in operative position and thus securely hold saidpiece against lateral movement towards the rail.

The changes in relative position of the parts in shifting the(lei-ailing piece from o erative to inoperative position are clearyshown in Figs. 1 to 4. Starting with the derailingpiece on 'the rail-asin Fig. 1, it willbe' seen that a pressure exerted in the direction ofthe arrow upon an operatin arm 21 or 22 will cause the lugs23, 24 toslide along the channels 14, 15 while the bolt 11 held stationary in thebracket supports and guides the derailing piece by means of slots 25,26. Said bolt 11 pivoted point upon which the derailing piece moves witha combined revolving and sliding therefore forms a fulcrum or motion orwhat might be called a tumbling action passing successively from theposition of Fig. 1, through the ositions shown in 2, and Fig. 3'-to theal position of Fig.- 4.

detailing position, the process is of course re- To close-thederailerpiece upon the rail in versed.-

ment of the operatin 22' is. small compare with the total move- It willbe, seen that the necessary moves rod attached at 21 or jment given thederailing piece which] is of either of its final considerable advantageon account of keep- 'ing within the standard movement of switch stands,interlocking plants, 'etc. At the same time it will be seen from Fig. 4,that the derailin piece is thrown entirely clear of and below t 1etrack, providing ample clear-v ance for assing cars. 7 seen; that instarting the derailing piece from positions, Fig. 1 or Fi 4, the liftingmovement is at first quite s ow,

making the action easy to start, but after the action is started itpicks up rapidly, and the derailing piece is thrown over quickly. Thisfeature togetherwith the fact that after the derailing piece passes overits central position I the movement is augumented by 1ts own .29, shownin Fig.

switch rod screwed into it from either side of weight, makes an e'asil[operated derailer and one which is thorough y reliable in its action.The ordinary switch rod connection may be bent to proper shapeand'attaclied to the 'operating arms 21, 2 2 or thespecial connection 2,may be used and the the rail. Two operating connections are shown, butany number may be used according to what signal connect ons,interlocking connections, etc., it is desired to use,

By our improved means for applying and securing a derailer to 'thebottom flange of the rail it will'be'appai'ent' that the derailer willbe .held incorrect position more rigidly and ermanently and will not beaffected by the s iftingof crossties as may be the case with derailerswhich are spiked to ties. Considerable latitude is also affordedwithregard ortion 30 at the rent end, a guideway i groovedinclineduideto size and sha e of rails. since as noted the bracket can eclamped to any width of rail base by lengthening or shortening theclamp, bolts 6, or by providing bolts long enough-for the'wide rail'bases, and simply ad'usting to fit the narrow rail bases. It will benoted that the clamp-J is so designed that the nuts of bolts 6 fitintoyrecesses therein and'when a wheel is derailed it falls .upon theinclined part 10 which tends to,

throw the wheel out awa from the'r'ail,- thus protecting the clamp bo tsand taking away undue strain from the clamp due to the wheel dropingupo'n it. V ur'im roved construction of the active portiono thederailing iece 18. constitutes i an important feature 0 the inventionand.

this we will now proceed to describe.
